' EXTENSBLE enormen-Fam.

To all wlw/'mn it may concern:

Be it known that I, ConNELrUs VAN DER y BOOM, a citizen ofI the United States, and a is clearly illustrated in Figs. 3 and therein being represented as lbroken away;

resident of Platte, in the county of Charles Mix and State of South Dakota, have invented a new and Im roved Extensible Picture- Frame, of whicli the following is a full, clear, and exact description.

p This invention relates to frames, and `especially to small, light frames such as used or holding pictures.

The objectof the invention is to produce a frame of simple construction which will be neat in appearance, and which can be adjusted so as to hold pictures of various dimensions within certain limits.

A further obj-ect is to construct the parts so 4as to enable the frame to be hung with its longitudinal axis in a vertical. or a horizontal pos1ti^n,-and to provide means for removably attaching a supportin leg to the back of the frame in such a way tlgiat theframemay rest upon a support' with its longitudinal axis in a vertical position or in a horizontal position.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Referenceis to be ing drawings forming tion in which similar characters of reference indi-cate corresponding parts in all the iigures. Figure 1 is a rear elevation, partly in section, of a frame constructed according to my invention, a portion of the 'picture held broken away; Fig. 2 is a vertical section on the line 2-2 of Fig. 1; Fig. 3 is a rear elevation of the main section at the end of the frame; Fig. 4 is an end view of the part shown in Fig. 3'; Fig. 5 is a rear elevation of one of the colnicos or corner pieces of the frame; Fig. 6 is an edge elevation of the lcorner piece or cornice shown in Fig. 5, theulper portion of this view being ig. 7 is a vertical section on the line 7 7 of Fig. 1, and upon an enlarged scale; this view ustrates the means for attaching the'supporting leg; and cross'section on the'line 8-8 of Fig. l.

Referrin morer particularly to the parts, and especia ly to Figs. 1 and 2, 1 and 2 represent respectively the upper and lower main Vsections of the ends of the frame. These members are similar in form; Ythe member 2 4. It

com rises a horizontal bar or rail 3, havin a longitudinal rabb'et groove 4 onits rear si e, and having a face late 5v attached to its for- This fece late 5 may be ornamented on its forward ace and may have an ornamental outer edge 6, as indicated; On

the sides of the frame il provide similar` sections 7 and 8, and these parts are formed with bars 9 which have longitudinal rabbet grooves 10 on their inner sides vlike the bars 3.

The corners of the frame are formed of 'cornices or corner pieces 11 which are similar to each other. These corner pieces have legs or sheaths 12 and 13, the former o1 which eX- tend longitudinally -of the frame and receive the bars 9 so as to act as guides *for them, as will be readily understood. The short legs 13 receive the bars 3 and act as guides. These 'sheaths are not rectangular in form but their inner sides are formed with elongated rabbet in Fig. 6. I provide these grooves 14 so that the cross section ofthe sheaths is made to iit nicely to the form orcross section ofthe bars, at the same time these rabbet grooves 14 constitute va shelf or ledge i to support the edges ofthe photograph vor picture 15 at the corners thereof. The legs 1'2 and 13 are 7provided with longitudinal slot-s 16 and 1 re'- Spectively, and through these slots clamping screws 18 pass, the said screws being receive in the bars runnin in the sheaths, as will be readily und erstood Each of these Screws 18 aiiords means for securin in position a clamping plate or clip 19 which projects over grooves 14, as indicated most 'clearly the edge ofthe photograph so as to hold the same in position, as shown in Fi 1. On the forwardsides of the rails or ars 9, face plates 20 are provided which are similar to the face plates 5 of the end sections.

he corner pieces 11 are formed with corner plates or face plates 21,which are of ornamental design, as shown. These corner plates are separated slightly from the sheaths 12 and 13 so as to form spaces which receive the ends of the face plates 5 and 20. The bars 3 and 9 are rovided with graduations orscales 22 whic read from the middle Y point of the bar; the divisions are half inches -and number consecutivelyzl I The' side bars are numbered 7, 8, 9, 10,:etc'.,wh1le the end It will-be evident that if the screws 18ers loosened', the bars Bland 9 will be telescoped more 'or less, as desired, in the sheaths, and the clamping screws 18 may.

then be tightened up so as to give theframe width, likewise if the endsl of the long.v

sheaths 12 are 1n alinement with the numerals ten of the bars 9, the frame will take a icture of ten inches in length, in this wa it 1s evident that the frame may be adjuste to vsuit pictures or photographs of variousdimenslons. l

On the rear side of the end section 1, there is' attached to the rail an anchor plate 23 as is shown in Fig. 7. To the upper edge of this anchor late a ring or eye 24 is attached which enablles the frame to be hung u as be readily understood. The o y of this plate 23 is offset from the rear face of the bar so as to form a pocket 25, and the lower portion of the plate 23 is bent outwardly so as to form an inclined lip 26. Near the point of juncture between the lip and the ody of the'plate, a transverse slot 27 is formed. This plate 23 is given this form so as to enable a rear leg 28 to be fastened in position. This rear leg is made extensible y means of telescopingi sections 29, 30, and 31, which are provide with slots 32, and clamglilg screws 33 running in the slots and affor g means for clampin the sections together rigidly, as will be readl yunderstood. The leg section 31 is formed below into an enlargement or foot 34, which rests upon the support for the frame when the frame is placed upon a table or'manteliece. The upper section 29 is bent upon itse f to form a downwardly projecting tongue 35, and the up er portlon of this tongue, Vwhere the materlal is doubled, is bent so as to beinclined to the direction of the body of the section.

Near this point, on its rear side, the leg section 29' is offset outwardly so as to form a head or nib 36, as shown. It should be understood that/this leg section 29 is resilient so that if the ton e 35 is thrust up` into the pocket 25, the ead or nib 36 will snap into the slot 27 and hold the leg in osition.

On one of its longitudinal si es the frame is provided with an anchor plate 37 similar to the plate 23, and having a ring 38 like the vring or eye 24.l The anchor plate 37 is constructed in all respects similarly to the plate 23 so that if desired, the leg 28 may be detached from the anchor late 23 and laced at the anchor plate 37. his enables t e leg to be used to support the frame on its long side. In this position, of course, the leg sections 29, 30, and 31 will be telescoped with each other so as to shorten the leg to its pro er length. The rings 24 and 38'are pivota y attached to the anchor plates 23 and 37 respectively, so that when the frame is not hung up they will fold up behind the frame so as to be concealed from view.

The frame is admirably adapted to be constructed of sheet metal or cardboard.- Attention is called to the manner in which the corner plates 21 overlap with the face plates carried by the bars. It should be understood' that even at the most extended position of the frame, these parts will still overlap so that the' frame always presents an'ornamental appearance.

Having thus described my invention, I

claim as new and desire to secure by Letters o Patent,-

An extensible picture frame having corner pieces with corner lates, and guide sheaths on the rear sides o said` lates, `side and end bars running in said s eaths and having face plates on the forward sides thereof overlapping said corner plates, clamping screws for clamping said bars in said sheaths, and clips carried by said clamping screws pro'ecting inwardly andholding the picture 1n t e frame. g l
